Horsehead from Kelling

Thanks Chaps

In the process of designing a new flat-field box for the 12", and sort the mirror movement which I suspect I have. Aim to get this done soon so when he pokes his head up at a reasonable hour, I can do him real justice!!

When I saw you with that sewage pipe sized tube I thought you had gone mad

But with results as nice as that, why not! Remember how we all went "ooooooooooooohhh!" as we saw it on your screen

Pics, pics, pics! Would like to see your new lightbox.

I think I need to do something similar as my flats aren't particularly accurate (whoever posted up the idea of stretching a t-shirt over the end of the scope - it doesn't work very well!)

Mike - see this thread http://stargazerslounge.com/imaging-discussion/114224-thoughts-using-el-wire-instead-el-panel.html

@TJ - so did many people who saw it!! I took it out to show a couple who were doing the rounds on Saturday.... Cue for plenty of double-entendres!!

That topic was an interesting read. I'm surprised with the large number of retailers selling a larger number of imaging products and yet there's nothing out there for producing easy flat fields.

Making a box is nice for home but not so good for taking out into the field, so to speak. Plus, I'm slightly put off making a box for a scope when I don't know how long I'll keep it (Change is a good thing ).

I'm intrigued to see how your project goes, Daz - and I'll be following SlySi84's lightbox progress 'n' all (Before I embark on any DIY myself )

That is a great image Daz, amazing for 3 subs.

But the field is probably where you need it most! You need to be taking flats with the camera in the same position/orientation/focus point as the lights, otherwise they ain't no good!!

Cheers Pete, hopefully add lots more to it later on....

What do you do at the moment to take your flats, Daz? What did you do at Kelling?

[daz]

For the ED80, I have an EL panel that just sits on top of the dew shield (scope points straight up).

At Kelling, I used "Sky Flats" - waiting until there was enough light in the sky to get through the Ha filter and using SkyFlats plug in Maxim to calculate the exposure needed and take the image... But would rather have the light box to get repeatable images of the same duration - bit more control available...

Wow! 2o min subs on a 12inch! GReat work! looks good.
